The spectra of photoabsorption of a trial electromagnetic radiation by a magnesium atom in the vicinity of the $3p^2\ ^1S$ autoionization state { AIS) have been calculated in the resonance approximation. The $3p{^2\ ^1}S$ AIS is connected with the $3p3d\ ^1P$ state by a strong laser field. A qualitative agreement has been obtained with the measured ion yield in two-photon ionization of magnesium vapors by bichromatic laser radiation for various laser frequency values.
